Suspension question (not mod-related)
Hey folks, just curious about a suspension oddity that I know nothing about whatsoever. So please excuse my ignorance 
I was lifting the vette up this afternoon for an oil change and some other stuff (ramps in the front, low-profile jack in the rear). I noticed that I couldn't fit the jack underneath the rear plus the usual 2x10 that I use for padding. Always done that in the past. So, I lifted it up using another method. After it had been sitting up for about 3 hours, I lowered everything back down.
Here's the question. Now the jack fits exactly how it used to fit along with the 2x10 on top. The back end of the car is now sitting about an inch higher than it was before the lifting.
Is this normal? Anyone able to explain what happened? This is the first lifting after it had been sitting still for about 8 months in the Wyoming winter.

car just settled IMO...once you lifted it the weighed of the wheels pulled on the suspension giving it a higher stance once you dropped the car. I guess sense the car sat for so long the car settled actually lowering it... thats my impression

After a bit of driving it will return to the previous location. Very common.

Hold your finger straight out and touch the wall. Now, without moving your hand pivot the finger down so it points at a 45 degree anle towards the floor. See how your finger moves away from the wall. Same thing happens with the suspension a-arms when you lift the car. Then, you drop the car back on the ground and the tires stick where they first get placed, holding the a-arm from extending out and up to it's origional location. Think of the a-arm as being wedged on an angle between the tire and the frame. Once the car is driven the wheels can slide out as they move ahead and the suspension goes back to it's origional position.
